Heavy Duty Leaf Springs for Trucks

Leaf springs are rugged, load bearing suspension components used in commercial trucks, trailers and other heavy duty vehicles. They consist of stacked, curved steel plates (known as “leaves”) that flex under load to absorb road shocks, support heavy weights and maintain vehicle stability. This simple yet durable design helps spread load forces across the vehicle’s frame and axles — making leaf springs perfect for work vehicles that carry changing or heavy cargo.

At Custom Truck One Source we offer a wide selection of suspension leaf springs engineered for heavy duty truck and trailer applications. Built from high strength materials and designed to withstand constant stress, these leaf springs improve ride stability, load handling and extend the life of your suspension system.
